Book of Ra Deluxe remains Greentube’s flagship slot and one of the most recognisable Egyptian-themed games ever made. It runs on a 5x3 layout with 10 paylines and features expanding symbols during free spins. The RTP typically sits around 95.02%, with volatility in the low-to-medium range. Its simple gameplay, strong theme, and win potential keep it popular even decades after launch.

This classic slot centres around a lucky fairy who brings multipliers, wild substitutions, and a 15-spin free spins round with boosted 3x or 6x payouts. It plays on a 5x3 grid with 10 paylines and an RTP around the 95% mark. Its clean design and consistent payouts have built it a large global fanbase.

A pure fruit-machine experience, Sizzling Hot Deluxe sticks to the essentials: 5 reels, 5 paylines, and medium volatility. With an RTP of 95.66%, it focuses on fast rounds and simple symbol hits, making it ideal for players who enjoy traditional gameplay without layered features.
Known for its underwater theme and rewarding free spins, Dolphin’s Pearl Deluxe offers a 5x3 layout with 10 fixed paylines. Wins with the dolphin wild pay double, and landing three pearl scatters awards 15 free spins with a 3x multiplier. RTP varies by version but generally sits around 95-96%.
